Ka taea te wehewehe i te aukati me te whakahaere i te parahanga i roto i te tukanga hanga pepa wharepaku kia rua ngā wāhanga: te maimoatanga taiao e mahia ana i roto i te whare hanga me te maimoatanga wai para i waho o te whare.
Te maimoatanga i roto i te tipu
Kei roto ko: ① te whakapakari i te whakaritenga (puehu, paru, kiri, pith, me ētahi atu), te whakamahi i te kiriata wai kohikohi puehu, te whakaiti i te parahanga puehu i roto i te awheawhe whakaritenga, te kohikohinga para, te whakaora i te kaha wera o te tahunga, pēnei i te whakamahi i te kiri rakau, te maramara rakau, te kohua tarutaru tahu; ② te tiaki wai, te hangarua wai mā, te maha o ngā whakamahinga wai; ③ te whakapai ake i te tangohanga o te wai pango tunu kai, te whakapakari i te whakahaere o te wāhanga horoi aukume hei whakanui ake i te maha o ngā wāhanga, te whakaiti i te nui o te wai pango tunu kai me te penupenu i tangohia mai i te horoi, me te whakamahi i te whakaora wai para tunu kai tino pai o ngā matū me te hangarau kaha wera, pēnei i te whakaora kawakore, me ētahi atu whakamahinga wai para. Me te whakamahi i te whakaora wai para tunu kai tino pai o ngā matū me te hangarau kaha wera, pēnei i te whakaora kawakore, me ētahi atu whakamahinga whānui o te hangarau wai para; ④ te whakamahana hauota hauota, te whakamahana oxy-alkali rānei, te whakamahana hauwai peroxide rānei, hei whakaiti i te tukunga o te lignin chloride, te chlorophenol me ētahi atu paitini wai para; ⑤ te wai paru i purea mā te tikanga tango mamaoa hei whakamahi anō hei whakaiti i ngā tukunga wai para o te whanariki me ngā mea wairewa; ⑥ te kohikohinga o te wai pango e rere ana me te turuturu, te wai matomato, te wai mā, me te mana rorohiko hiko hei ine i tōna kukū, ka tukuna aunoa ki te tāke e rite ana, hei whakaiti i ngā tukunga; ⑦ te whakaora i ngā muka ngaro, te whakaiti i te ihirangi o ngā totoka i whakatārewatia i roto i te wai para; ⑧ hei whakapai ake i te whakaora o te hopi turpentine sulphate, te whakaiti i te tukunga o ngā matū paitini; ⑨ te maimoatanga o ngā para totoka, te whakamahi i te tahunga hei whakaora i te wera, te whakamahi whānui me te whakakī i te poka o ngā momo maimoatanga e toru; ⑩ te maimoatanga o te puehu, ka taea te whakamahi i roto i te tango puehu hiko, te tango puehu kiriata wai me te wehewehe awhiowhio me ētahi atu taputapu; te tukatuka parahanga hau Wehewehe me ētahi atu taputapu; te maimoatanga parahanga hau, te kohikohinga o te hau kakara i roto i ia awheawhe, tae atu ki te hau kakara i whakaarahia e te kohu wai paru, i muri i te whakamatao, te maroke, te ātete-pahū me ētahi atu mahi, ka tukuna ki te kohua, te oumu whakaora kawakawa, te oumu raima rānei te maimoatanga tahunga; Te rongoā haruru, te mahi i ngā mahi hei whakakore i te wiri, te ārai haruru, me te huri ki ngā taputapu iti-haruru.
Te maimoatanga wai para i waho o te whare hanga
Ka tukatukahia te wai para mai i te putanga katoa o te tipu katoa i te taumata tuatahi, tuarua rānei i mua i te tukunga ki te wai, ka whakamahia rānei te wai para mō te whakamakuku, ā, ka whakamahia te oneone me ngā tipu hei pure i te wai para. Ko te maimoatanga tuatahi te nuinga o te tango i ngā mea kua tautau, mā ngā tikanga pēnei i te whakatō me te tātari me te whakamānu hau. Ka tāpirihia e ngā tipu takitahi ngā flocculants ki te wai para hei tango i ētahi o ngā mea waro colloidal kua rewa, pēnei i te lignin me ngā tae. Ka taea e te maimoatanga tuatahi whānui te tango i te 80 ~ 90% SS me te 20% BOD5. Ko te maimoatanga tuarua mō te maimoatanga matū koiora, ko te nuinga hei tango i te BOD5. He iti noa ngā tipu kua whakamahia ki Haina mō tēnei tikanga, tae atu ki ngā puna waikura, ngā tātari koiora, te papa hurihuri koiora me te paru whakahohe (tae atu ki te mimiti me te whakaora, te hau tere, te waikura whakapā). Ka taea e te maimoatanga tuarua whānui te tango i te 60 ~ 95% BOD5. I ngā whenua whakawhanake ahumahi, he tipu takitahi mō te tango tae tuatoru me te maimoatanga purenga wai para, kia eke ai ki te taumata wai inu, engari he nui te utu.
Kāore ngā pepa wharepaku Yashi e whakamahi ana i ngā maniua matū me ngā patu pepeke. Ka whakamahia te hangarau whakapūkara ā-tinana me te kore-whakamā hei whakarite kia kore he toenga paitini me te kino pērā i ngā matū, ngā patu pepeke, ngā konganuku taumaha, me ētahi atu. Kua whakamatautauria e te tari whakamātautau mana o te ao, SGS, ā, kāore he huānga paitini me te kino me ngā matū whakaputa mate pukupuku. He haumaru ake te whakamahinga, ā, he māia ake ngā kaihoko.
